I have to say that I was rather pleased by your performances & you must carry on your efforts. Nobody's perfect but you can work hard & achieve great things.
Some of you took extra care to create imaginary, though realistic (apart from Mulud & his mad partner;), personae (= imaginary/virtual character).
Here are the best ways to make a convincing oral final task:
-Prepare some clear & detailed notes on a piece of paper (not on your copybook = too heavy).
-In these notes, you must include the unit's new vocabulary (of course everything is related!), some specific grammatical constructions & some ideas or examples we discussed.
-Practise for your classmates or in front of your mirror before the D-day.
-Visualize the scene before it takes place. That will help you to get more relaxed.
I hope it helps a little!
